Boys are Girls and Girls are Boys: What's happening?

You may have noticed that there are a lot of people who don't identify with either of the two main sex genders, male or female.  (I am not trying to dispute that Lesbians, Gays, and Transgenders are not a gender class onto their own.)  What I am suggesting is that there are an increasing number of people who want their gender identity to be X, or them, or something like that. 

I was a bit confused when I first heard this, and just blamed it on Millenials being like Baby Boomers were when we all had to have Beatle haircuts.

But recently, I started noticing that there were a great many people, (non of whom I actually know), who seem to have characteristics that make them neither male or female.  I am making this statement based on their  overall look without reference to their sexual parts.  I have seen a lot of guys for instance who actually look like they could be girls.  In fact, they could be girls, but they look like they could also be guys!  My friends are noticing the same thing. 

The other day, I was at a reception hall, and I saw an employee behind the desk, and I could not figure out which gender they belonged to.  If took a few days and listening to them talk that I determined that they might be female. 

If you want to give me an argument that it should not matter what gender they are, that only their abilities should matter, let's not go there. This article is not about that.  It is about the blurring of male female differences. 

The question is:  Why is this happening? 

Is it a fashion statement?  Is it because there is too much plastic and hormones in the water?  Is it that my eyes are failing me in my old age?  Is the human genome changing? 

When I look at ants, and bees, I see highly specialized societies where sex is limited to a few members of the society:  the queen and a few males. 

Sometimes, I wonder if autistic people are the forerunner of specialized forms of humans of the future.  Highly functioning autistic people would easily fit this category.  But their autism might preclude them from having sexual relations, or reproducing.  (I do know one woman who is a high functioning autistic person, but her relationship with her husband is not what you would call warm, and almost a relationship of convenience for both of them.)

Perhaps these X, or thems, are also a forerunner of the future?  Non sexual beings ready to work as drones. 

Or perhaps it is just that we have so much medical waste seeping into the water table that we are now affecting how we as humans are developing. 

Not sure what is really happening here, but I thought I would put it out there just to see what anyone else has to say.
